2006-07-03 Paul Eggert <eggert@cs.ucla.edu>
Merge from coreutils.
* .cppi-disable: Add stdint_.h.
* .cvsignore: Add stdint.h.
2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
* xstrtod.c (XSTRTOD, DOUBLE): New macros, so that we can support
both double and long double versions.
(XSTRTOD): Renamed from xstrtod. Use DOUBLE internally.
* xstrtold.c: New file.
* xstrtod.h (xstrtold): New decl.
2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
* filemode.c (setst): Remove.
(strmode): Rewrite to avoid setst. This makes the code shorter,
(arguably) clearer, and the generated code is a bit smaller on my
Debian GNU/Linux stable x86 host.
2006-04-17 Paul Eggert <eggert@cs.ucla.edu>
* filemode.c: Include "filemode.h" first, to test the interface.
Assume that filemode.h includes sys/types.h and sys/stat.h.
(HAVE_ST_DM_MODE): New macro, moved here from ls.c.
(ftypelet): Reorder to put common cases first, for efficiency.
Add 'P', 'w'. Remove 'M', since it's now the caller's responsibility
to do 'M'.
(strmode): Renamed from mode_string, and now stores 12 bytes instead
of 10, for compatibility with FreeBSD. All callers changed.
(filemodestring): Now stores 12 bytes instead of 10, and sets file types
that can't be deduced solely from st_mode. First arg is now a const
pointer.
* filemode.h (HAVE_DECL_STRMODE): Include <string.h> for strmode.
(strmode): Renamed from mode_string.
(filemodestring): New decl.
* stat-macros.h: Don't undef S_ISDOOR, since it's never buggy.
(S_ISDOOR): Don't bother with S_IFDOOR, since that code is never needed.
(S_ISPORT, S_ISWHT): New macros, if not already defined.
2006-04-12 Paul Eggert <eggert@cs.ucla.edu>
* fsusage.c: Don't include <inttypes.h> or <stdint.h>, since
fsusage.h now does that. Include fsusage.h first, to test interface.
Prefer statvfs if it works, since it's blessed by POSIX. Attempt
at most one method (the old code could have generated decls that
didn't conform to C89, not that this was ever exercised).
* fsusage.h: Include <inttypes.h> and <stdint.h> if they exist.
2006-03-19 Jim Meyering <jim@meyering.net>
Work even in a chroot where d_ino values for entries in "/"
don't match the stat.st_ino values for the same names.
* getcwd.c (__getcwd): When no d_ino value matches the target inode
number, iterate through all entries again, using lstat instead.
Reported by Kenshi Muto in http://bugs.debian.org/355810, and by
Zouhir Hafidi in https://bugzilla.redhat.com/bugzilla/190656.
* getcwd.c (__getcwd): Clarify a comment.
Use memcpy in place of a call to strcpy.
2006-03-12 Jim Meyering <jim@meyering.net>
* fts-cycle.c (leave_dir): If cycle-check's saved dev-ino pair matches
that of the current directory (which we're about to chdir ".." out of),
then save the dev-ino of the parent, instead.
* same-inode.h (SAME_INODE): New file/macro.
* chdir-safer.c (SAME_INODE): Remove definition.
Include "same-inode.h", instead.
* same.c: Likewise.
* cycle-check.h: Include "same-inode.h".
(CYCLE_CHECK_REFLECT_CHDIR_UP): Define.
* cycle-check.c (SAME_INODE): Remove definition.
* root-dev-ino.h: Include "same-inode.h".
2006-03-11 Eric Blake <ebb9@byu.net>
* same.c (same_name): s/base_name/last_component/
* backupfile.c (check_extension, numbered_backup): Likewise.
* filenamecat.c (file_name_concat): Likewise.
2006-03-11 Eric Blake <ebb9@byu.net>,
Paul Eggert <eggert@cs.ucla.edu>
* dirname.h (FILE_SYSTEM_PREFIX_LEN): Move here from dos.m4.
[FILE_SYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]: Don't treat 1: as a
drive prefix.
(IS_ABSOLUTE_FILE_NAME): Treat all drive letters as absolute on
platforms like cygwin with FILE_SYSTEM_DRIVE_PREFIX_IS_ABSOLUTE.
(last_component): New method.
* dirname.c (dir_len): Determine when drive letters need a
subsequent slash. Preserve // when it is special.
(dir_name): Don't append dot when drive letter is absolute.
[TEST_DIRNAME]: Move into a full-blown gnulib test.
* basename.c (base_name): New semantics - malloc the result.
Preserve // when it is special. Preserve relative files that look
like drive letters.
(base_len): Preserve // when it is special.
(last_component): New method, similar to old base_name semantics.
* stripslash.c (strip_trailing_slashes): Use last_component, not
base_name. Strip redundant slashes from ///.
2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
* stdint_.h (intmax_t, uintmax_t): Prefer long to long long if

2006-07-03 Paul Eggert <eggert@cs.ucla.edu>
Merge from coreutils.
2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
* c-strtod.m4 (gl_C_STRTOLD): Add c-strtod.c to LIBSOURCES.
Require gl_USE_SYSTEM_EXTENSIONS, not gl_C_STRTOD, since we don't
want to require the building of c-strtod.o.
* lib-check.m4 (cu_LIB_CHECK): Remove SEQ_LIBM, since seq no longer
needs -lm directly.
* xstrtod.m4 (gl_XSTRTOLD): New macro.
2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
* lib-ignore.m4 (gl_IGNORE_UNUSED_LIBRARIES): Prefer binutils's
--as-needed option if available. Problem reported by Albert Chin in
<http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00114.html>.
However, use -Wl,--as-needed, not bare --as-needed, since HP-UX 11.11
cc merely issues a bunch of annoying warnings for --as-needed
(this problem was reported by Bob Proulx). Also, try linking with
-lm to detect a bug in binutils 2.16 (this problem was reported
by Ralf Wildenhues).
2006-06-18 Jim Meyering <jim@meyering.net>
Test for a bug that causes glibc's getcwd to suffer a failed assertion.
* getcwd-abort-bug.m4 (gl_FUNC_GETCWD_ABORT_BUG): New file and macro.
* getcwd.m4 (gl_FUNC_GETCWD): If we detect support for getcwd_null,
also check for glibc-2.4's abort-inducing bug.
* getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Fix typo.
Low-probability clean-up should be to use rmdir to get rid of
the just-created directory, not unlink.
* ftruncate.m4 (gl_FUNC_FTRUNCATE): If ftruncate is missing, make
configure fail, and request a bug report to inform us about it.
Add a comment that, barring reports to the contrary, in 2007 we'll
assume ftruncate is universally available.
2006-04-17 Paul Eggert <eggert@cs.ucla.edu>
* filemode.m4 (gl_FILEMODE): Check for strmode declaration.
2006-03-12 Jim Meyering <jim@meyering.net>
* chdir-safer.m4 (gl_CHDIR_SAFER): Add same-inode.h to the list.
* cycle-check.m4 (gl_CYCLE_CHECK): Likewise.
* same.m4 (gl_SAME): Likewise.
* root-dev-ino.m4 (gl_ROOT_DEV_INO): Likewise.
2006-03-11 Eric Blake <ebb9@byu.net>
* double-slash-root.m4: New file, provides gl_DOUBLE_SLASH_ROOT.
* dirname.m4 (gl_DIRNAME): Use gl_DOUBLE_SLASH_ROOT.
* dos.m4 (FILE_SYSTEM_PREFIX_LEN): Move from here to dirname.h.
(FILE_SYSTEM_DRIVE_PREFIX_CAN_BE_RELATIVE): New define.
2006-07-02 Eric Blake <ebb9@byu.net>
* wcwidth.m4 (gl_FUNC_WCWIDTH): Simplify by using AC_CHECK_DECLS.
